Application May 9, 1950, Serial No. 160,983

2 Claims.

This invention relates to an improved swivel fishhook, the primaryobject of the invention being to provide a more practical and efficientdevice of this kind, wherein the swiveling action is freer, and sidewiseplay between the rotatable components is substantially eliminated.

Another important object of the invention is to provide a device of thecharacter indicated above having a dual swivel arrangement wherein theeye and shank portions of the hook are independently rotatable relativeto each other and to means enclosing and connecting these portions.

Other important objects and advantageous features of the invention willbe apparent from the following description and the accompanyingdrawings, wherein, for purposes of illustration only, specificembodiments of the invention are set forth in detail.

In the drawings, wherein like numerals designate like parts throughoutthe several views:

Figure 1 is a side elevation;

Figure 2 is an enlarged fragmentary longitudinal section, taken on theline 2-2 of Figure 1;

Figure 3 is a transverse section taken on the line 3-3 of Figure 2;

Figure 4 is a side elevational View, on a reduced scale, of anotherembodiment, partly broken away.

Referring in detail to the drawings, the numeral 5 generally designatesthe swivel fishhook of Figures 1 to 3, comprising a hook 6 having astraight, round shank portion 7, an eye 8 having a straight, round shankportion 9, these shank portions having intermediate their ends theaxial,

hemispherical enlargements l and H, respectively, facing in oppositedirections with their round ends 12 directed outwardly and their planeends 13 directed inwardly. Rotatably circumposed on the shank portions 1and 9, between the enlargements I0 and II, is a cylindrical sleeve l4having plane ends I rotatably engaging the plane ends 13 of theenlargements l0 and I I. The sleeve I4 is of such length that theengagement of its ends with the enlargements maintains the inner ends l6of the shank portions 1 and 9 out of contact with each other for freeturning thereof relative to each other, as shown in Figure 2.

Enclosing and assembling the shank portions 1 and 9 and theirenlargements l0 and II, respectively, is the cylindrical, tubularhousing I! having hollow hemispherical ends l8 and I9, conformablyengaging the rounded outer ends ll of the enlargements l0 and H,respectively, and formed with axial holes 20, whose edges form journalbearings for the shank portions 1 and 9. The proportioning andarrangement of the parts is such that the shank portions turn freely inthe holes 20, the enlargements turn freely in the hemispherical housingends 18 and I9, and the shank portions 1 and 9 turn freely in the boreof the sleeve Hi, all without substantial endwise or sidewise movementrelative to each other, and the sleeve M is also freely rotatable in thehousing I! without undue looseness.

It will be obvious that with a fishing line (not shown) secured to theeye 8, the hook 6 can swivel freely relative to the eye 8 in eitherdirection, and that the freedom of both the eye and the hook to rotateindependently of each other precludes binding which is characteristic ofother devices of this character.

In Figure 4 is shown an embodiment involving, instead of the single hook6, a plurality of hooks 611 whose common shank portion la is journaledin the hole 20a of the adjacent hemispherical end |8a of the housing Ilaand has a hemispherical enlargement engaged with the housing end l9a,the device being otherwise similar to the device 5 of Figures 1 to 3.

I claim:

1. In combination, a tubular cylindrical housing having closed concaveends, shanks journalled axially through said concave ends, convexenlargements on said shanks within said housing and bearing rotatablyagainst the concave closed ends of the housing, the axially inward endsof the shanks being in axially spaced relation, and a sleeve circumposedon said shanks between said enlargements, with said enlargements bearingagainst the ends of said sleeve.

2. In combination, a tubular cylindrical housing having closed concaveends, shanks journalled axially through said concave ends, convexenlargements on said shanks within said housing and bearing rotatablyagainst the concave closed ends of the housing, the axially inward endsof the shanks being in axially spaced relation, and a sleeve circumposedon said shanks between said enlargements, with said enlargements bearingagainst the ends of said sleeve, said sleeve being cylindrical and beingrotatable in said cylindrical housing, the ends of said sleeve beingplane and the axially inward ends of said enlargements being plane.
